Site description

Duke Energy's Mayo Steam Electric Power Plant began operating in 1983, 11 miles north of Roxboro, North Carolina. It has a single coal-fired unit that can generate up to 727 MW of electricity per year. The plant is located on Mayo Lake, a popular boating and fishing destination. In August 2013, the State of North Carolina entered into a consent decree with Duke Energy regarding seeps and other un-permitted discharges to groundwater from the site.
